Abstract
An important component of most scuffing models is the concept of a critical temperature at which the lubricant film weakens to such an extent that a significant rise in friction coefficient occurs. This then causes a further rise in contact temperature and positive feedback ensues. However, scuffing models differ as to the location of the critical temperature and the mechanism by which it weakens the lubricant film in the contact.
In this paper a series of sliding tests have been carried out using steel on sapphire contacts, and the temperature of the contact and its environs has been mapped prior to and during scuffing using infrared emission radiometry. The results are compared with existing scuffing models, and the role of the contact temperature in scuffing is clarified.
